Fault Protection

The Nº500H series is designed to prevent damage to themselves and associated components. These extensive features protect both the critical circuitry of the amplifier itself and shield connected loudspeakers from serious damage due to high-power levels.

Basic protections designed into the Nº500H series include fuses on each amplifier channel to protect against excessive current conditions, such as driving shorted outputs. Inrush limiting prevents premature aging of the power supply components during power-up; once the power supply has been charged, this feature goes off-line until the amplifier is powered up again.

The Nº500H series actively monitors operating temperature, output current demands and the presence of DC on the outputs. The amplifier will shut down under any of these conditions and report the fault via the front panel LED and over the Ethernet connection. The amplifier must be shut down to clear the fault condition before being powered back up.

ML Net Fault Conditions

 

The slave devices in an ML Net system can report fault conditions

 

to the master device. Fault condition reports are displayed on the

 

display of the master device when the fault occurs. Some faults

 

may cause the amplifier to enter Standby mode. Power-cycling the

 

amplifier clears the fault condition, providing the

 

fault condition no longer exists.

Note

 

Some faults do not allow power to be reapplied to the amplifier until

 

the fault condition no longer exists to protect the amplifier from

 

damage.

 

 

The fault conditions reported are:

Slave Device DC Offset – indicates that the Nº500H series amplifier is experiencing a signal-related fault.

Slave Device Over Current – indicates that the Nº500H series is experiencing an over-current condition.

Slave Device Over Temperature – indicates that the Nº500H series amplifier is overheating.

Signal – indicates that the Nº500H series has experienced a general signal fault.
